Before heavy bombers of the Eighth Air Force struck at the marshalling yards in the city of Usti nad Labem (Aussig in German) in the north-western part of Czechoslovakia on April 17 and 19, 1945 fighter-bombers of the Ninth Air Force appeared on April 14, 1945.
According to U. S. archival sources eight Thunderbolts of a fighter group of the XIXth Tactical Air Command (the group number is not legible in the microfilm copy, unfortunately) dropped sixteen 260-pound bombs on what is believed "M/Y Aussig".
Martin Vesely wrote in his book on the air war over this territory – citing two wittnesses and the local authorities report that about 12 a.m. the chemical plant (Chemische Werke Aussig-Falkenau GmbH) and houses in the vicinity were damaged. Machine gun fire also broke windows at the hospital. Ten people were killed and some others wounded.
